ABSTRACT:
A case of plastic material for at least one marketable valuable piece as a coin, a medal, a precious stone, a pearl, a stamp or the like, including two superimposed elements, at least one of which is transparent and formed with a shell to lodge the piece. The elements are connected at least along their edges, and between the upper and lower elements which enclose the piece with certification data, a tamperproof seal is provided against counterfeiting and against forced opening. The seal includes a delaminable security printing pattern in the form of a hologram or of a multi-ink layer which is discontinuously adhered so as to be visibly and irreparably lacerated upon an opening attempt being imparted to the case.
